The EVO 300 Power is a stereo power amplifier by PrimaLuna that delivers 44 watts x 2 channels into 8 ohms in stereo ultralinear, or 85 watts into 8 ohms bridged to mono. Triode mode, switchable from the remote, delivers roughly half that. It was released in 2019. It is a 2-channel design using a Class A/B output stage. The EVO 300 Power is an all-valve design, running 4x EL34 output, 6x 12AU7 input. Biasing is Adaptive AutoBias. Bridged to mono it delivers 85 watts mono into 8 ohms, which is the usual way to use a pair of these on a demanding speaker. Speakers connect via binding posts. Its output transformer offers 4 / 8 / 16 ohm in stereo, 2 / 4 / 8 ohm in mono taps, and matching the tap to your speaker's impedance matters more here than a minimum-load figure would on a solid-state amplifier. The PrimaLuna EVO 300 Power has an MSRP of $4,695.
There are 5 PrimaLuna amplifiers in our database. Below you can see the main specs of these amps.
PrimaLuna Power Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The PrimaLuna EVO 300 Power is rated at 44 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 44 watts into 8-ohms
- 4 / 8 / 16 ohm in stereo, 2 / 4 / 8 ohm in mono output transformer taps - match the tap to your speaker's impedance

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
PrimaLuna EVO 300 Power is rated at 44 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the PrimaLuna EVO 300 Power with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
What size of room is the PrimaLuna EVO 300 Power Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the PrimaLuna EVO 300 Power amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

Bluetooth Connectivity
PrimaLuna EVO 300 Power doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your PrimaLuna EVO 300 Power. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
PrimaLuna EVO 300 Power doesn't have a phono input so in order to play your vinyl albums, PrimaLuna EVO 300 Power has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
PrimaLuna EVO 300 Power Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓44 watts per channel into 8 ohms.
- ✓A valve design running 4x EL34, which is the point of buying one.
- ✓Can be bridged to mono, so a pair can be used as two larger monoblocks.
- ✓Made in China.
- ✗Valves are consumables: they need replacing periodically, and often biasing, which a solid-state amplifier never asks of you.
- ✗A power amplifier has no volume control and no input selection - it needs a preamplifier, or a source with a variable output, in front of it.
- ✗It weighs 29.9kg - check the shelf, and plan on a second pair of hands.

How much power does the PrimaLuna EVO 300 Power have?
The PrimaLuna EVO 300 Power delivers 44 watts x 2 channels into 8 ohms in stereo ultralinear, or 85 watts into 8 ohms bridged to mono. Triode mode, switchable from the remote, delivers roughly half that.
Does the PrimaLuna EVO 300 Power use vacuum tubes?
Yes. The PrimaLuna EVO 300 Power is an all-valve amplifier: vacuum tubes do the amplifying from input to output. It runs 4x EL34 output, 6x 12AU7 input.
Does the PrimaLuna EVO 300 Power need biasing?
Biasing is Adaptive AutoBias. That means the amplifier sets the operating point of each output valve itself, so there is nothing to adjust and nothing to measure - you can change tubes without a meter or a screwdriver.
How long do the tubes in the PrimaLuna EVO 300 Power last?
Output valves are a consumable. In normal domestic use a set lasts somewhere between about 2,000 and 5,000 hours - a few years for most people - and they degrade gradually rather than failing outright. Input and driver valves last far longer, often the life of the amplifier. Check the warranty card before you buy: valves are almost never covered by the amplifier's own parts warranty, and are usually warranted separately for 90 days to a year.
What speakers suit the PrimaLuna EVO 300 Power?
A valve amplifier is judged on the speaker's sensitivity, not just on watts. At 44 watts, the safe rule of thumb is a speaker of about 90 dB or better - an insensitive speaker will run out of headroom long before the amplifier sounds bad. It also has 4 / 8 / 16 ohm in stereo, 2 / 4 / 8 ohm in mono output transformer taps. A valve amplifier has no minimum impedance the way a transistor amplifier does; you match the tap to the speaker, and a speaker whose impedance swings a long way will shift the tonal balance slightly because a valve amplifier follows that curve.
What amplifier class is the PrimaLuna EVO 300 Power?
The PrimaLuna EVO 300 Power uses a Class A/B amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Does the PrimaLuna EVO 300 Power have a built-in DAC?
No. The PrimaLuna EVO 300 Power has no built-in DAC, so a digital source such as a streamer or CD transport needs its own converter, or you connect it over analogue.
Can I connect a turntable to the PrimaLuna EVO 300 Power?
No. The PrimaLuna EVO 300 Power has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Does the PrimaLuna EVO 300 Power have Bluetooth?
No. The PrimaLuna EVO 300 Power does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the PrimaLuna EVO 300 Power have a headphone output?
No. The PrimaLuna EVO 300 Power does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the PrimaLuna EVO 300 Power cost?
The PrimaLuna EVO 300 Power has a manufacturer's list price (MSRP) of $4,695.
